Technician A says that the PCV system is designed tolimit CO emissions. Technician B says that catalyticconverters reduce HC emissions at the tailpipe. Whois correct?a. Technician Ab. Technician Bc. Both A and Bd. Neither A nor B
Which of the following statements about carbondioxide is not true?a. CO2 levels are highest when the air-fuel ratiois slightly leaner than stoichiometric.b. The production of CO2 is directly related tothe amount of fuel consumed; therefore,more fuel-efficient engines produce less CO2c. To reduce CO2 levels in the exhaust, engineers are working hard to decrease fuel consumption to keep CO2low.d. The concern for CO2 emissions is one of theprimary reasons for the delayed use of alternative fuels for automobiles.
Technician A says that black exhaust smoke is an indication of a too-rich air-fuel mixture. Technician B says that white smoke (steam) is an indication of coolant being burned in the engine.

- True or False? Engine misfires can cause a catalytic converter to overheat.arrow_forwardTechnician A says that the catalytic converter is used only to quiet the noise of the exhaust. Technician B says that the catalytic converter is used to alter the contents of the engines exhaust. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forwardWhile discussing the MIL on OBD II systems: Technician A says that the MIL will flash if the PCM detects a fault that would damage the catalytic converter. Technician B says that whenever the PCM has detected a fault, it will turn on the MIL. Who is correct? a. Technician A • Technician B • Both A and B • Neither A nor Barrow_forward
- fuel additive are being discussed. technician A says adding oxygenates to gasoline increases fuel economy. technician B says adding 10 percent ethanol to gasoline may boost the octane rating 2.5 to 3 points. who is correct?arrow_forwardWhile discussing EFI systems: Technician A says that the PCM provides the proper air-fuel ratio by controlling the fuel pressure. Technician B says that the PCM provides the proper air-fuel ratio by controlling injector pulse width. Who is correct? * 1 point a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forwardTechnician A says that gasoline can be used as a source of hydrogen for a fuel cell. Technician B says that carbon dioxide can be used as a source of hydrogen for a fuel cell. Who is correct?arrow_forward
- Technician A says that you may be able to smell antifreeze from a leaking heater core. Technician B says that you may be able to hear a loose belt when the engine is running. Who is correct? Select one: a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardan engine is being discussed for lean running condition. technician A checks for air leak in the intake. Technician B checks for alcohol in the fuel. who is correct?arrow_forwardAn engine starts and runs briefly after a small quantity of fuel is put into the spark plug hole, but it doesn't not start when fuel is added to the carburetor throat. Tech a says that the problem may be that the exhaust valve is not closing completely due to carbon buildup. Tech b says it may be due to a defective carburetor mounting gasket. Who is correct?arrow_forward
- technician A says lean ratio of 15:1 to 16:1 provide the best fuel economy. technician B says rich mixture have a ratio below 14.7:1 and provide more power from the engine but greater fuel combustion. who is correct?arrow_forwardTechnician A says there is less heat energy in high octane gasoline and, therefore less power is genorated during combustion. Technician B says usung a higher octane gasoline than required will not produce more power inless the engine has a knock sensor that allows the system to adjust ignition timing to take advantage of the higher octane. who is correct?arrow_forwardTrue or False? The diesel fuel’s antiknock quality ismeasured by the cetane ratingarrow_forward
